llo all wtont it' 'm/ctg/ concern:

Beit known that I, GUsTAvUs HEANNYOR WIsNER, a citizen of the UnitedStates, and a resident of Pioneer, in the county of Powell and State ofMontana, have invented a new and Improved Washing-Machine, of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in washing-machines, the objectbeing to provide a machine by means of which garments may be rapidly andthoroughly cleansed.

I will describe a washing-machine embodying my invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a top plan of a washing-machine embodying my invention. Fig.2 is a bottom plan thereof. Fig. 3 is a side elevation. Fig. 4 is asectional elevation. Fig. 5 is a side view of an inner tub employed.Fig. 6 is a bottom view thereof. plunger or pounder in elevation. Fig. 8is a bottom view of the plunger, and Fig. 9 is a side elevation oppositethat of Fig. 3.

Referring to the drawings, l designates a platform supported on suitablelegs 2, and arranged to rotate on the platform is a turntable 3. As hereshown, the turn-table is supported on antifriction-rollers 4, mounted onthe platform, and it has a central shaft 5, extended through an openingin the platform 1, and on the lower end of this shaft 5 areoppositely-extended arms 6, from the ends of which springs 7 extend toconnection with the platform, these springs being designed to move theturn-table in one direction, as will be hereinafter described.

Removably supported on the turn-table is an outer tub 8, which iscentered by lugs 9 on the platform, which engage with the outer side ofsaid outer tub. Removably placed in the tub 8 is an inner tub 10, inwhich the clothing is designed to be placed. The bottom of this innertub 10 is provided with radial corrugations 11, which rest upon thebottom of the tub 8, supporting the inner tub slightly above the bottomof said outer tub, so that water may readily pass through perforations12 in the bottom of the inner tub.

The upper end of the inner tub is provided with a ange 13, which byengaging with the inner surface of the tub 8 will hold the inner Fig. 7shows the tub in central position, and on the outer side of this innertub are spirally-disposed flanges 14. Movable up and down in the innertub is a plunger or pounder, comprising a concave upper portion 15 and aflat disk-like lower portion 16, provided with openings 17, throughwhich water may circulate as the plunger squeezes the clothing downward.Extended upward from a cross-head 1.8 on the plunger are rods 19, havingopenings 20 for receiving spring-arms21, extended from a shaft 22. Thesespring-arms provide for a yielding pressure of the plunger upon thematerial to be washed, and by providing a series of openings 20 in eachrod 19 the degree of movement of the plunger may be regulated. The shaft22 is supported in bearings 23 on a hinged cover 24, which is held downwhen the machine is in operation by means of springlatches 25. Byhinging the cover it is obvious that it may be raised when it is desiredto remove the tubs.

Connected to the shaft 22 is a segmentrack 26, which meshes with apinion 27, having its shaft-bearings in a standard 28, and on the shaftof the pinion is a bevel-gear 29, meshing with a segment-rack 3() on theupper side of the turn-table. At the opposite side of the turn-table isa segment-rack 31, designed to be engaged alternately by teeth 32 33,which are spaced apart on a wheel 34, which may be driven by anysuitable power. I have here shown a crank 35, connected to the shaft ofsaid wheel 34.

In ythe operation when the Wheel 34 is turned one set of teeth thereonby engaging with the rack 31 will turn the table 3 and the tubs, and theturning of the table through the medium of the gearing and the segment30 will cause a downward movement of the plunger or pounder. As the setof teeth 32 or 33 passes out of engagement with the rack 31, or, inother words, as the plane portion of the Wheel 34 passes over said rack31, the springs 7 will cause a quick reverse movement of the turn-tableand the tubs, and on this reverse movement the gearing will cause anupward movement of the plunger. On the downward movement of the plungerthe water in the inner tub will be forced through the clothing and outthrough the perforations 12 and thence up the sides of the inner tub,and upon the reverse rotary movement the iianges 14 will force the waterdown the sides of the inner tub and up through the perforations. It willtherefore be seen that IIO the water is kept in pi actically constantagitation.

It will be noted that the turn-'table has a peripheral lug 35, designedto engage with a cushion 36 on the platform to relieve the turn-tablefrom undue shock when it is moved by means of the springs.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A washing-machine comprising an outer tub and aninner tub having perforations in its bottom, spirally-disposed flangeson the outer side of said inner tub, means for rotating the tubs and aplunger operating in the inner tub.

2. A washing-machine comprising an outer tub, an inner tub, means forimparting rotary motion to the tubs, the said inner tub having itsbottom corrugated and perforated, spirally-disposed flanges on the outerside of the inner tub, and a plunger for operating in the inner tub.

3. A washing-machine comprising a platform, a turn-table mountedthereon, tubs supported on the turn-table, a gearing for moving theturn-table in one direction and a spring for moving the turn-table inthe opposite direction.

4. A washing-machine comprising a turntable, outer and inner tubssupported on the turn-table, a plunger for operating in the inner tub, amutilated gear mechanism for rotating the turn-table in one direction, aspring for rotating the turn-table in the opposite direction, andgearing operated from the turn-table for imparting up-and-down motion tothe plunger.

5. In a washing-machine, a platform, a turn-table mounted thereon, innerand outer tubs supported on the turn-table, a shaft eX- tended from thecenter of the turn-table through the platform, oppositely-eXtended armson said shaft, spring connections between said arms andthe platform, asegmentgear on the turn-table at one side, a mutilated gear-wheel forengagement with said segment gear or rack, a segment-rack on theopposite side of the turn-table, a segmentrack having gear connectionswith said lastnamed rack on the turn-table, and a plunger operatedthereby.

6. In a washing-machine, a platform, a turn-table mounted thereon, innerand outer tubs supported on the turn-table, a gearing mechanism forimparting a partial rotary movement to the turn-table in one direction,a spring mechanism for moving the turn-table in the opposite direction,a plunger in the inner tub, a shaft-spring arm connections between thesaid shaft and the lunger, and means actuated by the turn-tab e forimparting mot-ion to the shaft.

7. In a washing-machine, a platform, a turn-table thereon, a tubsupported on the turn-table, a segment-rack on the turn-table, abevel-gear engaging with said rack, a pinion on the shaft of thebevel-gear, a segmentrack engaging with the pinion, a shaft to whichsaid last-named segment-rack is attached, a plunger having connectionwith said shaft, and means for imparting reciprocating rotary movementto the turn-table.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
